To all whom it may concern: rels of the body portionof the hinge a piece Be it known that I, VVILLIAM J. KEENE, a g of tubing is out of proper length, as shown citizen of the United States, residing at Ohii in Fig. 10 and from the opposite ends of the cago, in the county of Cook and State of Illi tubular blank thus formed, extend the pronois, have invented certain new and useful I jections Or flanges a and a. By means of Improvements in Hinges, of which I dodesuitable dies the tubular blank shown in Fig. Clare the following to be a full, clear, and eX- l 10 is first brought to the flattened shape act description, reference being had to the shown in Fig. 11 and afterward by suitable accompanying drawings, forming part of this dies to the shape shown in Fig. 12 of the specification. drawings. In bringing the tubular blank to his inventionhas relation more particui the finished form shown in Fig. 12, the oppolarly to that class of hinges commonly known site central portions of the tube are brought as double-acting spring hinges, although firmly into Contact to form the web portion features of the invention will be found appli- I A that extends between the spring barrels cable to hinges ofother types. Examples of B and B, and the projections or flanges a double-acting spring hinges of the type to f and a" are folded down over the upper and lower edges of the web portion A as clearly which my invention more particularly relates are illustrated in Patent No. 620,933 shown in Figs. 1, 5 and 12 of the drawings.

In order to give greater rigidity to the web granted to Joseph Keene March 1 1, 1899.

The invention has for its Object toprovide portion A of the body and as well also to 1m [prove the ornamental appearance of said an improved construction of spring hinge that shall be cheap, durable and effective and portion, the web A is ofiset by means of suitthe invention consists in the features of novable dies as indicated atthe points a and a elty hereinafter described, illustrated in the of the drawing.

Each of the bearing sleeves The body of the hinge comprises the web C is formed with a vertical lug or offset 0 (see portion A and the spring barrels B and B. Figs. 6 and 7) that enters the vertical groove The web portion A and the barrels B and B or channel I) formed at the junction of the are formed integral and from a single piece of I barrels B and B with the sides of the web tubingpreferably seamless tubing, as inportion A of the hinge body. The vertical dicated in Figs. 10, 11 and 12 of the draw-I lugs or olIsets 0 thus securely lock the bearingsf i. I lfOI'Hllllg the web and spring baring sleeves O to the barrels B and B and consequently hold the upper end of the spring D rigid with respect to said parts.

In the lower end of each of the spring barrels B and B sits a bearing sleeve E, the reduced inner portion of which is formed with a slot 6 to engage the lower end at of the spring D. Each bearing sleeve E is shown as formed with a head portion e provided with radial holes 6 adapted to receive a pin F whereby the bearing sleeve E is interlocked with the corresponding swinging leaf or side of the hinge. Preferably, each of the lower bearing sleeves E is of smaller diameter than the barrel of the hinge wherein it sits and this reduced portion of the sleeve E is encircled by a tubular bushing G having an annular flange g that extends between the lower end of the hinge barrel and the head portion 6 of the sleeve E. This tubular bushing G is preferably formed of steel or like hard wear resisting metal and in order to hold it against rotation with respect to the spring barrel wherein it sits, this bushing Gr is preferably formed with an offset adapted to enter the slot or channel 1) formed at the junction of the lower portion of the spring barrel with the side plates of the web A (see Figs. 3 and 8).

The leaves or wings H and H of the hinge will be formed from sheet steel plates, each of these wings or leaves being provided with the upper and lower ears 7t and h that are perforated to receive the retaining bolt K. The ear h of the leaf H sits over and rests upon the top of the bearing sleeve C, and similarly, the ear h of the leaf H extends across the end of the bearing sleeve E. At the upper end of the retaining bolt K is formed a cap or head K, more or less ornamental as desired, and the lower end of the bolt K is screw-threaded as at k to enter a correspondingly threaded socket formed in the lower head or cap K In order to securely hold the cap K in proper osition upon the bolt K and prevent its wor ring loose or becoming displaced, the cap K is formed with a series of notches or seats k (see Fig. 9) that will be engaged by corresponding oflsets 71, formed upon the ear 72, of the adjacent hinge-leaf. The offsets k are preferably formed by bumping out the metal of the ear 7L at such points. Preferably also the upper ear h of each hinge-leaf is provided with similar offsets it that will sit within seats k formed in the lower face of the upper cap K. In order to permit the metal of the ears h and h to yield slightly as the cap K is secured firmly to position, thereby causing the seats k to override the offsets h,

the adjacent outer faces of the bearing sleeves C and E are formed respectively with the spaces 0 and 6".

By my present invention an exceedingly cheap and durable hinge is produced. By

forming the spring barrels integral with the web portion of the hinge body, and without jointbetween the barrels and the web portion, the web portion that is subjected to the greatest strain is formed at its ends with three thicknesses of the metal plate and by this construction a thinner plate may be used than would otherwise be rerpiired. So also by uniting the upper and lower edges of the web portion of the hinge body by means of flanges or o'll'sets formed integral with the web, a most effective locking together of the plates that comprise the web is secured, and the necessity for employing rivets for uniting the plates is avoided. Obviously, the spring hinge shown in the drawing may be used either end up according to its position upon the door frame.

It should be noted that the overlapping flanges a and a. extend between the barrels B and B for the entire width of the connecting web A and form rigid braces between the barrels. By this means the hinge body is strengthened at the point of greatest weakness, namely, at the ends of the junctures between the springbarrels a d the web. Moreover, the upsetting and overlapping of the flanges a and (1/ serves to temper and strengthen the metal at the ends of the connecting web, so that the hinge body is greatly strengthened at the parts subjected to the most strain.

It will be understood that the precise details of construction above set out may be varied without departure from the spirit of the invention and that features of the invention may be employed without its adoption as an entirety.

Having thus described my invention, what I claim as new, and desire to secure by lietters Patent, is

1.
